demet akyol‌, Sorry I've been away... Your external GPS device needs to be supported by Apple (MFi program) and the manufacturer should provide the so called protocol string(s) which needs to be included in your app's info.plist, as Joe pointed out. Then once the device is peered up with an iPhone or iPad using Blue tooth or a cable, your app using Apple ExternalAccesory framework should be able to connect to the GPS device and receive NMEA string data from it. Please refer to the code I posted in this thread previously. NMEA sentence is a comma delimited string data. I only studied and parsed the GGA, GSA and RMC sentences for location data. The following is the GGA sentence as an example. Hope it helps.

Thanks Michael. I did not publish the service. Have passed on the info but haven't got anything back yet. We are also suspecting it might be caused by some data problems... ... View more

Hi Michael, There are point, line and polygon layers in the feature service. I didn't publish the service but I believe it was published using ArcMap 10.6 or above. The ArcGIS Server is 10.4.1. Thanks, Shimin ... View more

Hi Nick, Thanks a lot for your reply. I tried your suggestions but the subtypeField and featureSubtypes are all empty. Loading the geodatabase: I know the HFDHarvestPoly layer has subtype defined but as you can see the subtypeField and featureSubtypes are empty:  What am I doing wrong? Would you have any idea of how to implement subtype support? Thanks, Shimin ... View more
